Local WISP Broadband Distribution Network

Project Overview

This infrastructure project details the design, implementation, and operations of a private Wireless Internet Service Provider (WISP) serving over 140+ concurrent client stations in peripheral residential areas in Tiznit, Morocco. The network provides high-availability broadband distributions over license-free 5GHz frequencies.

Technical Specifications & Features

• Point-to-Multipoint (PtMP) Topology: High-gain outdoor base stations distributing signals across sectors to subscriber client stations (CPEs).
• Dynamic Route Engineering: Handles dynamic Layer 3 routing configurations to ensure path failovers and network scalability.
• Bandwidth Capacity Management: Applies dynamic shaping limits per user subscription class to optimize network throughput under high contention ratios.

Technical Stack & Technologies

• Operating Systems: RouterOS (MikroTik Core Routers), Pharos OS (TP-Link Antennas)
• Hardware: TP-Link Pharos CPE610/CPE510 arrays, MikroTik Cloud Core Router
• Protocols: OSPF (Open Shortest Path First), PPPoE, TDMA (MAXtream)
• Management APIs: Python API wrappers (for diagnostics automation)

Core Infrastructure Engineering Practices

• Layer 3 OSPF Routing Backbone: Configured dynamic OSPF multi-area routing parameters to establish dynamic routing path redundancies, guaranteeing fast failover convergence.
• Hierarchical Token Bucket (HTB) Shaping: Designed advanced HTB queue structures and simple QoS queue trees inside RouterOS to shape bandwidth and prioritize latency-critical traffic classes.
• Layer 2 Access Layer Hardening: Implemented strict MAC bridge filters, static ARP bindings, isolated client bridges, and PPPoE tunnel authentication layers to prevent DHCP spoofing, ARP poisoning, and network sniffing threats.
• RF Propagation Modeling: Formulated links using Fresnel zone clearance reviews, link path attenuation checks, and active RSSI metrics to ensure high CCQ link stability.
